“…Figure 1 shows the in vitro antioxidant capacity of the extract before and after the in vitro digestion. The overall antioxidant capacity obtained for the extract is in accordance to that reported by Beres et al [17]. Results indicate that after the digestion process, the extract still possesses antioxidant properties.…”

“…TPC of the extract was 114.6 ± 10.5 mg GAE/g and after in vitro digestion, TPC significantly decreased (p < 0.05) to 11.9 ± 1.0 mg GAE/g. Data on TPC of the extract are in agreement with those reported by Beres et al [17]. Figure 1 shows the in vitro antioxidant capacity of the extract before and after the in vitro digestion.…”

“…During digestion, transformation of polyphenols chemical structure and/or formation of complexes with food matrix macromolecules can occur resulting in the modification of bioactivities [17,18]. Particularly, anthocyanins have been found to be degraded by the transition from the gastric environment (acidic) to the intestinal environment (mild alkaline) and the effect of pancreatin and bile acids [19].…”

Diabetes pathogenesis encompasses oxidative stress, inflammation, insulin malfunctioning and partial or total insulin secretion impairment, which leads to a constant hyperglycemia. Polyphenols are known to possess bioactive properties, being Tannat grape skin a natural and sustainable source of these compounds. The present study aimed to find out the bioaccessibility of health-promoting molecules composing a multifunctional extract from Tannat grape skin obtained under hydro-alcoholic-acid conditions. The identification of phenolic compounds in the samples was performed by ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS). Subsequently, the samples were in vitro digested mimicking the human oral gastrointestinal conditions and the bioactivity of the digest (antioxidant, anti-inflammatory and modulation of glucose metabolism) was assessed. Effect on glucose metabolism was estimated by measuring carbohydrases activity and the functionality of glucose transporters of small intestine cells in presence and absence of the digested extract. Flavonoids, phenolic acids and phenolic alcohols were the major phenol compounds detected in the extract. The bioaccessible compounds protected the intestinal cells and macrophages against the induced formation of reactive oxygen species (ROS) and nitric oxide (NO). In addition, glucose transporters were inhibited by the digested extract. In conclusion, the bioaccessible compounds of the extract, including phenols, modulated key biochemical events involved in the pathogenesis of diabetes such as oxidative stress, inflammation and glucose absorption. The extract was effective under prevention with co-administration conditions supporting its potential for either reducing the risk or treating this disease.

“…According to Beres et al (), in a more innovative definition of fibers, polysaccharides can be associated to phenolic compounds and may associate antioxidant properties to fiber benefits. Thus, is is interesting to evaluate fiber content and antioxidant capacity of desserts to define the best formulation to be tested in vivo.…”

The present study aimed to verify the antioxidant capacity in vitro of baru almond, evaluate the effect of baru intake on gastrointestinal transit and biochemical profile in rats and based on such results characterize the chemical composition of a baru‐enriched dairy dessert and analyze its effect in vivo. It was observed that traditional dairy desserts hastened the gastric emptying and delayed intestinal transit. Ingestion of dairy dessert with baru slowed gastric emptying and avoided the delay of intestinal transit time. After baru consumption, the biochemical profile was extremely favorable with reduced triglycerides and very low‐density lipoprotein, and increased high‐density lipoprotein‐c. The results show that baru almond is a good source of lipids, fibers, and antioxidants (1,179 mg GAE kg−1 sample by ABTS and 8,342 mg GAE kg−1 sample by ferric tripyridyltriazine). The dairy desserts with the highest content of baru normalized gastrointestinal transit compared to traditional dessert, and improved biochemical parameters in rats. Pratical applications In our work, we have developed a new dairy dessert with a Brazilian almond called Baru. The manuscript is significant because it demonstrates the presence of lipids, fibers, and antioxidants in high levels in baru almond and the health benefits associated with the intake of these compounds in dairy desserts.

“…Grape pomace, a mixture of skins, pulp, seeds, and stems, obtained after pressing of grapes in the winemaking process, represents about 20–30% wt of processed grapes [ 1 , 4 ]. The valorization of grape pomace is important considering either the environmental issues [ 5 ] or the applications of its bioactive compounds [ 6 , 7 , 8 ]. However, in the last decade only 3% of grape pomace was turned into animal feed [ 9 , 10 ], as compost [ 11 , 12 , 13 ], or other applications as thermal insulation for buildings [ 14 ].…”

Effect of Nanoconfinement of Polyphenolic Extract from Grape Pomace into Functionalized Mesoporous Silica on Its Biocompatibility and Radical Scavenging Activity

The aim of this paper is to assess the properties of Mamaia (MM) grape pomace polyphenolic extract loaded onto pristine and functionalized MCM-41 mesoporous silica as potential ingredients for nutraceuticals or cosmetics. The chemical profile of hydroalcoholic polyphenolic extracts, prepared either by conventional extraction or microwave-assisted method, was analyzed by reverse-phase high-performance liquid chromatography with photodiode array detector (HPLC-PDA) analysis, while their radical scavenger activity (RSA) was evaluated using DPPH (2,2-diphenyl-1-picrylhydrazyl radical) and ABTS (2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) assays. The extract-loaded materials were characterized by Fourier transform infrared (FTIR) spectroscopy, N2 adsorption-desorption isotherms, thermogravimetric analysis, as well as RSA (DPPH and ABTS assays). The polyphenols release profiles from pristine and functionalized (with mercaptopropyl, propyl sulfonic acid, cyanoethyl and propionic acid moieties) MCM-41-type supports were determined in phosphate buffer solution (PBS) pH 5.7. For selected materials containing embedded phytochemicals, cellular viability, and oxidative stress level on immortalized mouse embryonic fibroblast cell line (NIH3T3) were evaluated. A more acidic functional groups linked on silica pore walls determined a higher amount of phytochemicals released in PBS. The extract-loaded materials showed a good cytocompatibility on tested concentrations. The embedded extract preserved better the RSA over time than the free extract. The polyphenols-loaded MCM-41-type silica materials, especially MM@MCM-COOH material, demonstrated a good in vitro antioxidant effect on NIH3T3 cells, being potential candidates for nutraceutical or cosmetic formulations.
